Just a thought that hasn't been addressed on this thread yet.
If someone stumbles upon one of my pieces which I consider subpar, but wants to purchase it, should I go ahead and sell it? Being that I'm an up and coming (read: starving) artist, I would feel grateful that someone liked it enough to want to buy it.
Maybe later in my career it'll come back to haunt me, but I'd probably risk it for a sale now. If someone asks 30 years from now, I'll just tell them my little brother painted it.
Any thoughts on this?
